All of the above B. Retinol and retinal are ligands while retinoic acid acts only in the visual cycle. To do this the cell interprets the genetic code and for each group of three letters it adds one of the 20 different amino acids that are the basic units needed to build proteins.

O The shape of a protein determines its function. The key difference between gene expression and gene regulation is that gene expression is a process that produces a functional protein or RNA from the genetic information hidden in a gene while gene regulation is the process that induces or represses the expression of a gene.
